value with thresholds set to determine what the music would be. While missions used the dynamic music system too, the music was laid out more like a movie with set music occurring for specific events. The music of the game was inspired by the city, meant to be "organic" compared to the industrial and electronic music of the first Infamous. The score was released as two soundtracks, Infamous 2 The Blue Soundtrack and Infamous 2 The Red Soundtrack. Sucker Punch was using around 30% of the Cell processor by the end of Infamous, and for Infamous 2, they were "creeping up over 50 and 60%, because [they] know how to put things on to the Cell processor." With the additional power, Sucker Punch was able to "have more characters on-screen, more complicated shaders, and much greater layering". For the game, a new method of ambient occlusion (AO) was developed, a hybrid of precomputed AO and dynamic AO. The new method was used to render contact shadows and self-occlusion for moveable objects and was meant to complement the other methods of AO already used. On March 1, 2011, Sucker Punch announced a mission creation feature for Infamous 2 that had been in development since 2009. A limited beta for testing this feature was released in April 2011. Sucker Punch wanted to give players a way to continue enjoying the game after completing it and felt there was immense pressure to incorporate multiplayer and that many games were tacking it on. They considered cooperative gameplay, though found it did not make for an experience you wanted to keep playing, saying "ultimately, the game still ends." In October 2011, it was announced that PlayStation Move support would cover the whole game as part of an update which would come out sometime after Infamous: Festival of Blood was released, along with a new cutscene creation tool for the UGC creator. The update was released on November 2, 2011.

On February 18, 2011, before the game's release, Special Edition and Hero Edition versions of Infamous 2 were announced for pre-order.
